Unsuccessful splitting into multiple lines when using generics.

Describe the style change

I came across a strange formatting of the function declaration in the presence of generic typing. As a minimal example, I will give a function with one argument:

def func[T](argument: argument_type) -> return_type:
    pass

In this example, type T is not used, but you can also come up with a function in which type T is used, for example, using collections.abc.XXX[T] instead of argument_type and return_type.

It is assumed that the maximum length of the line has been changed, in this example, the value 50 is used (black -l 50 ...).

It seems to me that it is worth first trying to split arguments into several lines, and only then trying to separate generic declaration.

Examples in the current Black style

def func[
    T
](argument: argument_type) -> return_type:
    pass

Desired style

def func[T](
    argument: argument_type
) -> return_type:
    pass

Additional context

My black version:

$ black --version
black, 23.11.0 (compiled: no)
Python (CPython) 3.12.0
